What else can I help you with?
When do participants in swmming maximize friction when do they minimize it?
you maximumize friction to train and when you compete you minimize it
How do you minimize friction in a car?
To minimize friction in a car, ensure that the tires are properly inflated, as under-inflated tires increase rolling resistance. Regular maintenance, including oil changes and lubrication of moving parts, helps reduce internal friction within the engine and drivetrain. Additionally, selecting high-quality lubricants and using smooth, aerodynamic designs can further decrease air resistance and friction, enhancing overall efficiency.
List and Explain 2 reasons why you might increase friction between two objects?
Car tires and the road: increasing friction will allow a car to brake faster. Shoes and the ground: increasing friction will make it less likely for you to slip.
What are the forces acting on the cars and explain why the cars do not slide down the hill?
The car is being acted upon by gravity and friction. The reason that the car doesn't slide down the hill is because friction is keeping the car in place.
How is friction cut down in a car engine?
Friction in a car engine is reduced by using proper lubrication, such as engine oil, to create a smooth surface between moving parts. Additionally, improving the design and materials of engine components can help minimize friction. Regular maintenance and keeping the engine's parts clean can also help reduce friction.
What is a situation in which friction is not helpful?
Friction can be unhelpful in situations where you want to minimize energy loss, such as in machinery where friction causes wear and tear on moving parts, reducing efficiency. Additionally, in sports like speed skating or car racing, reducing friction can help increase speed and performance.
What are the ways to minimize friction?
To minimize friction, you can use lubrication between surfaces, ensure surfaces are smooth and clean, reduce the force pressing surfaces together, and use materials with low friction coefficients.
What is a feature of a car that increases friction?
the front boot of the car increases the friction on the car
What can be done to minimize the effect of friction?
To minimize the effect of friction, you can use lubricants between surfaces, choose materials with lower friction coefficients, reduce the contact area between surfaces, and ensure proper surface smoothness to reduce frictional resistance.
What is a Friction on car example?
A common example of friction in a car is the friction between the brake pads and the rotors when you press the brake pedal to stop the car. This friction helps convert the car's kinetic energy into heat, slowing down the car.
If friction acting on the car is the action force then what is the reaction force and what object does it act on?
The reaction force to the friction acting on the car is the friction force acting on the road. It acts on the car in the opposite direction to the friction force acting on the car.
Explain how a moving car can become positively active?
A moving car can become positively charged through processes like friction, which can cause the transfer of electrons between the car and another object. For example, when the car drives on the road, friction between the tires and the ground can result in the car gaining a positive charge if electrons are transferred from the road to the car.
